APPLICATION OF GEO-NATURAL FIBERS AND SUBGRADE CONSTRUCTION

Abstract

The use of geo-natural fibres in subbase and subgrade construction is a new and environmentally friendly way to improve the mechanical qualities and durability of road and pavement infrastructure. The inclusion of various geo-natural fibres, such as jute, coconut, and sabai grass, into the subbase and subgrade layers of road building is investigated in this study. These natural fibres are environmentally friendly and locally available, making them an appealing alternative to typical building materials. The study looks at how these fibres affect the engineering properties of subbase and subgrade layers, such as tensile strength, load-bearing capacity, and resistance to soil erosion. The findings show that using geo-natural fibres improves soil stabilization, reduces settlement, and increases resilience to moisture-induced damage. This study highlights the importance of sustainable construction techniques by encouraging the use of bio-based materials that lower the environmental imprint of infrastructure development. The findings have significance for low-cost, ecologically friendly road construction technologies, particularly in areas where natural fibres are abundant.
